Answer:

The lines are perpendicular to each other because -8 and \frac{1}{8} are opposite reciprocals of each other.

Step-by-step explanation:

The  first line has equation y=-8x-\frac{5}{4}.

The slope of this equation is -8.

The second equation is y=\frac{1}{8}x+\frac{4}{5}

The slope of this equation is \frac{1}{8}

The two slopes are negative reciprocals of each other.

This means that the two lines are perpendicular.

In a class of 24 people, the ratio of women to men is 3 to 1. How many women are in the class?
ryzh [129]

Answer:

There are 18 women in the class

Step-by-step explanation:

First of all this is a ratio topic and to solve it one needs to know that ratios are fractions so to solve it we will find first the sum of the fractions which is 3+1 and =4. Fully recognising through the question that the fractions or relation of the women to the men in the classroom is in a 3:1 ratio, we should multiply the fraction with the total number of people in the class which bring forth the result as 18!

I am Lyosha [343]
The medium sized orange would have 62 calories. To divide by 1/5, which in decimal form is 0.2, you just multiply 310 by 0.2, therefore, giving you 62. Hope this helps!
